5) Indication Accuracy

Voltmeter:

Fixed Range: 19.99 V / 199.9 V / 1999 V

Accuracy: ± (0.5 % rdg + 1 digit) at 23° C ± 5° C

 

Ammeter:

Fixed Range: 1.999 A / 19,99 A

Accuracy: ± (1% rdg + 1 digit) at 23° C ± 5° C

6) Safety Precaution

a.) Fuse at the primary side (Commercial power source will be cut at the time of failure.)

b.) Thermal fuse is incorporated inside the power transformer. (Excessive heating during the time of abnormal operation will be prevented.)

c.) Fuse inside the internal power circuit (Circuit will be cut when it fails.)

d.) Forced air cooling type (fan) has a temperature sensor inside. (Operation stops when the fan becomes out of operation.)

7) Operating Environment

Temperature: 0° C ~ 40° C

Humidity: 10 % ~ 80 % (Condensation and corrosive gases should be avoided.)

 

Storage Environment

Temperature: ­ 10° C ~ 60° C

5) Rating

a. Constant Voltage

Line Regulation: 0.01 % + 2 mV (to Input Voltage ± 10 %)

Load Regulation:0.01 % + 5 mV (to 0 ~ 100 % Load)

Note: Measured at the sensing terminal for models

Ripple: Within 1 mV (10 Hz ~ 1MHz rms) for models of which output voltage is not greater than 65 V. Within 5 mV (10 Hz ~ 1 MHz rms) for models of which output voltage is not less than 65 V.

Transient Response: 50 µsec typical

The time required for the output voltage to recover to a value within the rated voltage 0.01 % + 2 mV at the time of 10 % ~ 100 % fluctuation of output current.

Temperature

Coefficient: 100 ppm/ °C typical

b. Constant Current
